Description

- Patented Feb. 11, 1930 PATENT OFFICE MAX GR'UNBAUM, OF BROOKLYN, NEW YORK CELLULAR PRODUCT AND METHOD OF MAKING THE Ho Drawing.

This invention relates to cellular products such as paper, wall paper, paper board, paste board and like materials produced from paper or like cellular pulp, containing as a constituent part thereof an insecticidal, germicidal and fungicidal material which is non-' odorous, non-poisonous, or substantially or relatively non-poisonous to mammals and which can be added to the pulp from which such products are made without causing any material deterioration thereof and which is substantially unaffected in the process of producing such products from the pulp treated therewith. p The invention is more particularly concerned with paper, paper board, paste board, and like materials produced from paper, but primarily wall paper, treated in accordance with this invention to render such products insect, germ and fungus proof. The invention also relates to the process of roducing such insect, germ and fungus proo products. It is well known that for many uses paper and other cellular products of the character referred to above have been found to be highly objectionable because of the fact that such products are subject to injurious attack by insects and fugi and also because certain paper or pulp products such as wall board and wall paper are unsanitary and provide breeding laces for germs, insects and the like. These ob ectionable features, particularly the .latter in regard to wall paper, have resulted in the discontinua nce of the use of certain paper products with consequent loss to manufacturers of such products.

I have discovered that these objectionable features can be obviated and that satisfactory insect, germ, and fungus proof products can be made by incorporating a non-odorous insecticide, germicide and fungicide which will not injure or be injured by paper or like pulp with the materials from which the products.

are to be produced, before forming the products or applying such protective material to the finished product. I prefer to employ an organic insecticide, germicide and fungicide and of such organic insecticides I prefer to use an organic insecticide which has been derived from the bark of the cinchona tree here- Application filed May 8, 1928 Serial No. 276,203.

inafter referred to as a cinchona derivative. Among the materials so derived and which are particularly adapted for use in the practice of my invention, may be mentioned quinine, quinidine, cinchonine and cinchonidine. Although all of these materials, or anyone of them, may be employed with success, Iprefer to use cinchonine (C H N O) or its salts. These materials, in addition to being odorless insecticides are germicides and fungicides as well, and are non-poisonous or at the most only slightly poisonous to mammals. The taste of these materials is extremely bitter and offensive.

In the preferred ractice of my invention I mix about 0.04 of a pound of cinchonine with each 100 pounds of the cellular material which forms the stock from which the insect proof article is to be produced. After adding the insecticide to the pulp or stock, the paper, 70 paper board, wall paper, paste board or'the like is produced in any usual or desired manner and the product is not deleteriously affected by the presence of the cinchonine and the cinchonine is not deleteriously affected by the process of producing the paper or the like from the thus treated pulp.

In producing paper and like products which are insect proof, germ proof and fungus proof according to my process, the insecticide may not only be-added to the materials from which the paper, paste board or the like is to be formed but it may be added to the clay or other filler or size which may be employed in or upon the surface of the paper or the like. In addition, the protective material may be incorporated in the coating material when s'o-called coated papers are being produced. Also, in the case of wall paper and other paper products which are substantially completely covered with a printed design I may advantageously incorporate the protective material in the printing ink and impregnate the'paper product with such material during the printing thereof.

In place of cinchonine or other cinchona derivative I may with some measure of success employ sodium fluorid or a silicofluoride but I prefer touFe a cinchona derivative.

As heretofore stated, my invention is preferably emplo ed in the manufacture of wall described having cinchonine incorporated paper and li e cellular wall coverings and therein.

when so used the cinchonine or equivalent material is preferably added in the proportions set forth to the pulp, filler, size, printing ink or the like used in producing the wall cover- Ily invention is also particularly adapted for use in preparing paper products for packaging food and other materials which are subject to deterioration due to the attacks of insects, germs, fungi and the like.

While I have described in detail the preferred practice of my process and the materials which I prefer to employ it is to be understood that I am not limited thereto except as set forth in the subj oined claims.

I claim:

1. The herein described process of making products roduced from cellular material insect proo which comprises incorporating a cinchona derivative therein.

2. The herein described process of making 4. The herein described process of making insect proof, germ proof and fungus proof wall paper and like cellular material which comprises adding a cinchona derivative to the material from which such products are formed, and forming the paper and like cellular material therefrom.

5. The herein described process of making insect proof, germ proof and fungus proof Wall paper and like cellular material which comprises adding a compound of the quinine group to the material from which such products are formed, and forming the paper and like cellular material therefrom.

6. The herein described process of making insect proof, germ proof, and fungus proof wall paper and like cellular material which comprises adding cinchonine to the material from which such products are formed, and forming the paper and like cellular material therefrom.

7. The herein described process of producing insect proof paper comprising adding a cinchona derivative to the material from which such products are produced, and forming the paper therefrom.

8. The herein described process of producmg insect proof paper comprising adding cinchonine to the material from which such products are produced, and forming the paper therefrom.

9. A cellular product of the character described having a cinchona derivative incorporated therein.

10. A cellular product of the character In testimony whereof I aflix my signature.
